Subjective and Objective data work hand in hand. Each is limited on their own, one certainly cannot replace the other, and there are limitations even with both together. I would not be in favor of replacing population surveys with harvest surveys but I am all in favor of using both congruently. To suggest that harvest surveys couldn’t provide an added benefit to population management??? If you have a tool box full of tools, why use just one?
My entire academic and professional career has centered around clinical research and that did include subjective data that was extremely valuable, even though you have to account for the fact that it is indeed subjective and dishonesty or simply misinterpreting what is asked in surveys is a factor. This doesn’t make me an expert on anything any more than anyone else, but surveys for game management are far from a waste of time and money, and most harvest surveys I have completed while subjective are very straightforward: Did you hunt? Did you kill? If so, what, when, and where? I could lie through my teeth the whole way through but because I like to hunt, I don’t. I would say most people still fit that bill…of course that is subjective.
